Abstract
The invention claims a non-poisonous pesticide and a preparation method thereof, wherein the non-poisonous pesticide is constituted by the following raw materials in parts by weight: 100 parts of water, 20-33 parts of neochamaejasmin, 20-30 parts of tripterygium wilfordii alkaloid, 12-30 parts of nicotine and 30-35 parts of sophocarpidine. The preparation method comprises the following steps of: taking 100 parts of the water, 20-30 parts of the tripterygium wilfordii alkaloid, 12-30 parts of the nicotine and 30-35 parts of the sophocarpidine in parts by weight to mix, agitating and adding ethanol to adjust the pH to obtain pesticide stock solution. The effect of the pesticide on various insect pests, spots and bacteria of fruit trees, vegetables, crops and tea leaves is obvious, the pesticide effect is quick and the pesticide effect duration is long without pesticide residue after use; the raw materials are natural medicinal plants and are easy to obtain; plant essences in the raw materials are nutritional elements needed for the growth of sprayed plants; the production process is safe and environmental-friendly, no harmful matters such as wastewater and waste gas are discharged, and the production process is friendly to the environment.
Description
technical field [0001] The invention relates to a non-toxic pesticide insecticide and a preparation method. Background technique [0002] With the continuous improvement of people's living standards, the consumption concept of urban and rural residents has changed a lot. People are no longer satisfied with having enough food and clothing. They not only pay attention to nutrition but also pay more attention to non-toxic and harmless food. However, more than 60% of the pesticides currently used in my country are chemical preparations, and the chemical residues in agricultural by-products mainly come from chemical fertilizers and pesticides. More than 50% of chemical pesticides contain carcinogens. Due to the serious excess of chemical pesticide residues, agriculture suffers from the erosion of harmful pesticides to varying degrees, the ecological environment is severely damaged, and the lives of organisms are threatened. endanger their own survival. [0003] At present, bota...
